566 BABOONS CHAP. Society's Gardens a year or two back : the young was observed to take both teats of the mother Into its mouth at once. Mr. Sclater1 In a recent list of the group allows forty-seven species, of which thirty-three were examined by himself. Subsequently, however, the list has been reduced to forty by the same authority. One of the rarest species Is C. stairsi, first described from a skin stripped from a specimen which lived for a short time at the Zoological Gardens. The genus Cynocephalus (or Papio) includes the Baboons ; and the scientific name indicates the Dog-like aspect of these animals, due to the projecting snout. Gynoeepfacdus Is confined to Africa and Arabia. Several of the species of the genus are well known. The Mandrill, G. mormon (or maimovi), has blue ridges on the muzzle, the bridge of the nose being red. The animal lives in herds, and Is ferocious and omnivorous. Hie Chacma Baboon, G. porccurius, Is the largest of Baboons. It lives in South Africa in large herds. The Arabian Baboon, G. hamadryas, Is the Sacred Baboon of the Egyptians, The names of two other species, 'G. thoth and G. anu'bis^ serve also to remind us of the ancient Egyptians. There are altogether eleven species of Gelada (or Theropithecus) is separated as a distinct genus. Though regarded as a Baboon, Garrod has pointed out many points of likeness to Gwcopithscus? The two species are, like the other Baboons, African. GynopitJiecus niger is a small black Baboon from Celebes. It has swellings on the muzzle as in other Baboons, but differs from them in being a more amiable creature as well as in Its smaller size. It has a rudimentary tail, smaller even than the small tall of the typical Baboons. It has, like them, Ischial callosities. In the second sub -family, Semmopithiecinae, the following characters are distinctive : — All the Apes of this group are slender in form, with a long tail. There are no cheek pouches. The stomach is sacculated ; it is divided into three portions. This is accompanied by an apparently more exclusively vegetarian diet than characterises other Apes, which mingle with their diet of fruit a large proportion of insects, eggs, etc. 1 f<Oi3L a new African.
